Answer:
Step-by-step explanation:
Adjacent to the undetermined angle is 6, and the hypotenuse has been given. We can conclude, after looking at our SOHCAHTOA, that we will be using cosine(CAH) to solve this problem.
Let the unspecified angle be 
(This sign is called theta, which is just a sign for angle)
Lets start!
cos = adj/hyp
cos = 6/13
= 
(6/13)
= 62.5
= 63
Hope that helped!
Hello! I can help you with this! It asks for a ratio, so we have to solve it in that format. Although, there are different ways of solving it.
1. Okay. So a ratio for this would be 3/4 : 5/6. To divide fractions, we must keep the first fraction the same, change the division into a multiplication symbol, and flip the second fraction over. So it would look like this: 3/4 * 6/5. Multiply straight across (n*n/ d*d). When you do that, you get 18/20 or 9/10 in simplest form. The landscaper's rater is 9/10 acres per hour.
2. The ratio for this question is 9/4 : 1/2 For the next question, we repeat the steps for dividing fractions. Keep, Change, Flip. 9/4 * 2/1 is 18/4 or 4 1/2 in simplest form. Sally's running speed is 4 1/2 miles per hour.
3. Okay. Going back to question #1, the unit rate was 9/10 acres per hour. All we have to do now is multiply that number by 4. To multiply fractions, do it straight across. 9/10 * 4/1 is 36/10 or 3 3/5 in simplest form. A landscaper can mow 3 3/5 acres in 4 hours.
4. Then we repeat the steps done in question #3, and incorporate it in this problem. Going back to question #2, the unit rate was 4 1/2 miles per hour. All we have to do is multiply by 3. 9/2 * 3/1 is 27/2 or 13 1/2 in simplest form. Sally can run 13 1/2 miles in 3 hours.
